My laptop is running fine.but before this reply I never mention about a problem (little though) with my Dell Wireless Bluetooth Mouse.

Sometimes the mouse get disconnected; there's no exact duration. I thought it was because of the battery power.But today now I boot my system to Win 7, and there is no problem with the mouse, i didn't change the batteries of the mouse.

Current driver in Win 8 for the bluetooth module is http://support.lenovo.com/en_US/downloads/detail.page?DocID=DS031999&rss=true

I had a similar problem. The driver you listed is not what you want to install. You want to the use the drop down menus on the right side of ATI's web page to select notebook, the adapter mobile and then the os version. You get taken to a page to download a driver verification tool. Installing this driver then prompts you to download a different driver, which has mobility in the name. I downloaded this and installed it and it's been great since.

We have upgraded with the latest BIOS as well as with the new mobility display driver. However, my seconday display connected to the HDMI port is not displaying correctly. The desktop image is not taking to complete screen size (1920 x 1080 recommended resolution). I lose about ½ inch all around the display. If I select 1680x1050, then the desktop image takes the full screen.

I have a dell studio 1558 core i7, exact issues (TDAS777 mentioned), i have been experiencing since i installed windows 8 pro (x64).Studio 1558 is a famous product of Dell, they should not be this much lazy in releasing New Drivers for Studio 1558 compatible with windows 8 (all versions of windows 8).

Oh DELL personnel please dont forget Studio 1558. It was 1 of your FAMOUS Product, which some customers are still using...

Then why hasn't this been asked for in sufficient multitude by Studio 1558 owners if that is the case?

It would also if that right is to be taken at face value make far more sense to have ALL supporting drivers in place upon Windows 8's release and certainly before the promotional price for uptake and installation/registration expires on January 31.

Too often with this sort of thing it's people wanting to pull their hair out in anger and frustration at a botched install while others supposedly pat themselves on the back at their apparent ingenuity in doing it successfully.

When people are paying cash for upgrades to their PC's that Microsoft says should be perfectly compatible with a new Microsoft operating system if that is what they want to do then the PC manufacturer should be assisting them to to sort out any identified compatibility issues so that it just works for everybody without any mystery.

When this does not happen too many people are made to feel inept when it is the lack of support and undisputed knowledge so as to not make any upgrade instead of a clean install a farce that is inept.
